No, that message was about the incoming scenario. I am new to Courier,
it may be the case that Courier always throws 550 before accepting mail
into the queue, so it would be the default behavior as described in
prior email. If a message with invalid sender and recipient addresses is
given to a server which throws 550, then the doublebounce is generated
on the sending server. If it's accepted into the queue, then a bounce
and a subsequent double bounce is going to be on the receiving server.
Which may or may not be what you want. Personally, I gave up on
double bounces, as most of them are SPAM, and there are too many of them
to watch over.
